A helob]ect of this invention isto provide .new and improved vIneens for mounting a solid rubbertire on a Wheelwhich will hoiti .the tire firn'ily in place, which will readily admit of the removal and repi:: 1.':in.r ci the tireV or a section thereof when Worn'.

'2 0' A further object of my invention is to provide in n wheel of this character new and improvedmeansfor preventing the wheel r`om-'skidding i With these objects in view and with the `215V intention of securingother vadvantages hereinafter appearing, this 'invention consists `in certain .features of construction and com y `binations of parts hereinafter described in lthe specificationypointed out in the clsims iand Illustrated in the accompanying drawthe accompanying-drawings, Eigurel deze view in elevation,'ivith a small part in yelection oftagrrheel embodying my invention.

Onerend members formed 1n-4 i centrally y arrmiged ,band-10, vvhich v is supported on the `parallellv arranged members of the spokes, and a pair of rings ll one of'wluch is arranged at each side.of

the band lO'and is spaced therefrom and seid rings 11 are supported by the diver ent members of the spokes. There is there ore formed in the rim, between each ring 1l and the band l0, a tire-receiving annular space or slot 12. The inner edges of the rings 11 and the edges of the bund 10, which together of course form the edges of the tire-receivmg arrangement es will hereinafter appear. The solid rubber tire sections are shown at 14 and are provided with beveled edge'sat their bases corresponding to the beveled edges of the tire receiving slots 12. On the inside of the rim at each side of the Wheel mounted e. flexible strip 16 which is made wide enough to span the tire receivin slot l2. After the strip is inserted the en. are -weided together forming a complete band, or, if desired, the ends of the strip may .be .lapped over each other. These-'bands 16 are supported by rods 17 which are mounted in enf-is of the spoke members andl the rods 1T nre'held a, einst displacement by ins `18. When the ro bends 16 are forced tightly against the bases ci? the solid rubber tire sections and the beveled edges of the tire sections are shun-pcd against theb'eveled edges of theV tire-receiving slots 12 so that the tire sec tions are securely heldin place on therim.

in band l() are formed a series of cir cumferentially extending slots 20,V and there are .preferably as many of these slots :as Athere are spokesin the wheel, and each slot is arr-an 'ed so thatthe center thereof is in line wit the shank portion of the spoke.

- These slots 20 are primarily designed to -receive non-skidding elements, shown at 21, which may be made of rubber,-vvood or also be utilizedfor receiving id rubber tire sections. The ends'of the spokes 8 adjacent t the band 10 "are slhtly thickened, and the inner surr as shown m22., j

faces t ereof are concave, the twjo surfaces together form-lng a socket. At the centerv of' the at surface '7 on the of a coil spring isarrange `over the lng slots l2, are beveled to provide a clencher s 17 are driven into pace the n roc V241:, and the othere'nd thereof is -inserted in the socket f omledby the curved surfaces 22. On the inner face of the band 10 between the adjacent ends of-the slots are arranged )racket members 28 in which are mounted pins 26 and 27. One end of a bow yspring 29 is secured to each pin 27, and the bow spring then passes over the end of a coil 'spring 25, and the other end of the bow spring rests freely on the pin 26 in the bracket member at the opposite end of the slot 20 -under which sald spring extends. The bow springs 29 therefore form bottom 4 supports for the non-skidding elements 21,

.of said rim and supportin and in conjunction with the coil springs 25 hold the said non-skidding elements in p0- sition. What- I claim is l. The combination of a wheel rim having three tire-receiving slots extending length- Wise around the same, and spokes supporting saidrim, each spoke comprising a middle pair of radial parallel members supporting the middle part of the rim, and an outer pair of members diverging 'outwardly from the inner end of the spoke to the outer edges y the outeredges of the rim, cushion tires 1n the two outer slots, and spring supported tread blocks in the middle slot. 5

2. The combination of a Wheel rim, having a row of slots extending lengthwise around the same, spokes'supportin the rim, tread blocks in the slots, exible p ates su ported b the rim and bearing against e inner si es of the blocks, and springs in compression betweenthe spokes and the plates. 0

3. The combination ofva wheel rim having a row of slots extending lengthwise around the same, spokes supporting' the rim, tread blocks extending through said slots, spring plates" extending lengthwise behind the blocks and supported at their opposite ends on-the rim. and coiled springs between the spokes and the middle art of the plates.

ln 'testimony whereof, I sign the forego ing specification, in the presence of two wit# masses.
